Cleavage and Oligomerization of Malondialdehyde

Tetrahedron, 1993
Abstract Malondialdehyde (MDA) slowly self-condensates in aqueous solution at pH 4.5–6 and room temperature yielding (E)-(3′-oxo-1′-propenyl)malondialdehyde and 2,4-dihydroxymethylene-3-(2′-oxoethyl)glutaraldehyde. The latter compound exists in solution in equilibrium with 4-(1,3-dioxopropan-2-yl)-5-formyl-2-hydroxy-3,4-dihydro-2H-pyran, the trans ...

Methyl malondialdehyde as an internal standard for the determination of malondialdehyde

Journal of Chromatography B: Biomedical Sciences and Applications, 2001
Methyl malondialdehyde (Me-MDA) is suggested as an internal standard for the determination of the lipid peroxidation product, malondialdehyde (MDA). A procedure for synthesising the Me-MDA sodium salt is described in detail. The purity and identity of the synthesised Me-MDA have been confirmed using nuclear magnetic resonance and UV spectroscopy, and ...

Malondialdehyde measurement in urine

Journal of Chromatography B: Biomedical Sciences and Applications, 1994
Malondialdehyde (MDA) is an end product of lipid peroxidation and is a frequently measured index of these processes. The thiobarbituric acid (TBA) test is commonly used to measured MDA, but its specificity is questionable due to the presence of interfering chromogens.

An indo investigation of the structure and bonding in malondialdehyde and lithium malondialdehyde

Journal of Molecular Structure, 1975
Abstract The geometries of the enol forms of malondialdehyde and its lithium analog have been investigated using the INDO MO method in its original parametrization. The former molecule is predicted to have a planar, symmetric structure nearly identical with that of acetylacetone.

Malondialdehyde Derivatives in Urine

1988
Malondialdehyde (MDA) excretion in rat urine is responsive to peroxidation of dietary lipids and to factors which increase lipid peroxidation in vivo: vitamin E deficiency and administration of iron, CCI4 or adriamycin. Urinary MDA is also increased by administration of the lipolytic hormones ACTH and epinephrine and by fasting, particularly when the ...

Unequivocal demonstration that malondialdehyde is a mutagen

Carcinogenesis, 1983
Malondialdehyde (MDA), a product of lipid peroxidation and prostaglandin biosynthesis, has been reported to be mutagenic and carcinogenic. Recent evidence suggests, however, that strongly mutagenic impurities are generated during the preparation of MDA that may contribute to the observed biological activity.

Effect of malondialdehyde on nitrosamine formation

Food and Cosmetics Toxicology, 1980
Abstract Several aldehydes associated with foodstuffs were investigated for their effect on the formation of N-nitrosodimethylamine and N-nitrosodiethylamine. Whereas glucose, furfural, benzaldehyde and glyoxal had little influence on nitrosamine formation, malondialdehyde, which can be derived from lipids by peroxidation, greatly influenced the ...

Ascorbate and malondialdehyde in stroke patients

Irish Journal of Medical Science, 1994
It is believed that free radical formation and subsequent oxidative damage in the form of lipid peroxidation may be a factor in the cerebral damage secondary to the ischaemia of a cerebrovascular accident (CVA). Total serum ascorbate and malondialdehyde (MDA) were measured in 45 patients with CVA on the day of admission to hospital (Time 0) and 48 ...
